C# 调用存储过程简单完整的实例代码

using System.Data.SqlClient;
private void Page_Load(object sender, System.EventArgs e)

{ // 在此处放置用户代码以初始化页面
String DBConnStr; DataSet MyDataSet=new DataSet();
System.Data.SqlClient.SqlDataAdapter DataAdapter=new System.Data.SqlClient.SqlDataAdapter();
DBConnStr=System.Configuration.ConfigurationSettings.AppSettings["ConnectString"];
System.Data.SqlClient.SqlConnection myConnection = new System.Data.SqlClient.SqlConnection(DBConnStr);
if (myConnection.State!=ConnectionState.Open)
{ myConnection.Open(); }
System.Data.SqlClient.SqlCommand myCommand = new System.Data.SqlClient.SqlCommand("P_Test",myConnection);
myCommand.CommandType=CommandType.StoredProcedure; //添加输入查询参数、赋予值
myCommand.Parameters.Add("@Name",SqlDbType.VarChar);
myCommand.Parameters["@Name"].Value ="A"; //添加输出参数
myCommand.Parameters.Add("@Rowcount",SqlDbType.Int);
myCommand.Parameters["@Rowcount"].Direction=ParameterDirection.Output;
myCommand.ExecuteNonQuery();
DataAdapter.SelectCommand = myCommand;
if (MyDataSet!=null)
{ DataAdapter.Fill(MyDataSet,"table"); }
DataGrid1.DataSource=MyDataSet; DataGrid1.DataBind(); //得到存储过程输出参数
Label1.Text=myCommand.Parameters["@Rowcount"].Value.ToString();
if (myConnection.State == ConnectionState.Open) { myConnection.Close();
}
}
